Despite its reputation as an operating system exclusively for professionals and hardcore computer hobbyists, Debian's open development cycle and strict quality control have helped it to gain popularity. With an installed base that’s growing annually by an estimated 25 percent, Debian clearly has its fair share of fans (not to mention the newsmaking Debian-based Linux distributions such as Knoppix, Ubuntu, and Xandros). Unlike other popular Linux distributions, the Debian GNU/Linux operating system favors text-based configuration over graphical user interfaces (GUIs). In The Debian System, author Martin Krafft, an experienced Debian developer, introduces the concept of the Debian operating system, and explains how to use its various tools and techniques as well as the pitfalls and the thinking behind each. Debian may appear simplistic, but it is actually quite robust, scalable, and secure. After reading The Debian System, you’ll see that strict adherence to standards, highly experienced developers, a clear vision and goals, and a certain degree of academic perfection make Debian the exceptional system that it is today. This is a fascinating, must-have volume that UNIX and Linux administrators will find complements the standard Linux references and will quickly orient you to Debian's unique philosophy and structure. Co-published with Open Source Press, an independent publisher based in Munich that specializes in the field of free and open source software.

Debian GNU/Linux, a very popular non-commercial Linux distribution, is known for its reliability and richness. Built and maintained by an impressive network of thousands of developers throughout the world, the Debian project is cemented by its social contract. This foundation text defines the project's objective: fulfilling the needs of users with a 100% free operating system. The success of Debian and of its ecosystem of derivative distributions (with Ubuntu at the forefront) means that an increasing number of administrators are exposed to Debian's technologies. This Debian Administrator's Handbook, which has been entirely updated for Debian 8 “Jessie”, builds on the success of its 6 previous editions. Accessible to all, this book teaches the essentials to anyone who wants to become an effective and independent Debian GNU/Linux administrator. It covers all the topics that a competent Linux administrator should master, from installation to updating the system, creating packages and compiling the kernel, but also monitoring, backup and migration, without forgetting advanced topics such as setting up SELinux or AppArmor to secure services, automated installations, or virtualization with Xen, KVM or LXC. This book is not only designed for professional system administrators. Anyone who uses Debian or Ubuntu on their own computer is de facto an administrator and will find tremendous value in knowing more about how their system works. Being able to understand and resolve problems will save you invaluable time. Learn more about the book on its official website: debian-handbook.info

Building Wireless Community Networks is about getting people online using wireless network technology. The 802.11b standard (also known as WiFi) makes it possible to network towns, schools, neighborhoods, small business, and almost any kind of organization. All that's required is a willingness to cooperate and share resources. The first edition of this book helped thousands of people engage in community networking activities. At the time, it was impossible to predict how quickly and thoroughly WiFi would penetrate the marketplace. Today, with WiFi-enabled computers almost as common as Ethernet, it makes even more sense to take the next step and network your community using nothing but freely available radio spectrum. This book has showed many people how to make their network available, even from the park bench, how to extend high-speed Internet access into the many areas not served by DSL and cable providers, and how to build working communities and a shared though intangible network. All that's required to create an access point for high-speed Internet connection is a gateway or base station. Once that is set up, any computer with a wireless card can log onto the network and share its resources. Rob Flickenger built such a network in northern California, and continues to participate in network-building efforts. His nuts-and-bolts guide covers: Selecting the appropriate equipment Finding antenna sites, and building and installing antennas Protecting your network from inappropriate access New network monitoring tools and techniques (new) Regulations affecting wireless deployment (new) IP network administration, including DNS and IP Tunneling (new) His expertise, as well as his sense of humor and enthusiasm for the topic, makes Building Wireless Community Networks a very useful and readable book for anyone interested in wireless connectivity.

A guide to Ubuntu covers such topics as installation, configuration, the filesystem, the command line, system maintenance and security, networking, using OpenOffice.org, Web browsing, and playing games.
